Chandrima Bhattacharya, the newly appointed state president of the Trinamool Congress (TMC) in West Bengal, has resigned from her post just a month after taking charge.Her resignation comes amid growing dissent within the party, with several MLAs rebelling against Mamata Banerjee's leadership.The TMC recently suffered a major defeat in the West Bengal Assembly elections, which has exacerbated internal tensions.

Bhattacharya's decision to step down marks a significant setback for the ruling party, as she had been appointed during an organisational overhaul by Chief Minister Mamata Banerjee.

In her resignation letter dated July 4, 2026, Bhattacharya stated she was disassociating herself from the TMC, citing the ongoing rebellion in both Parliament and Bengal.This development adds to the challenges faced by the TMC, which is already grappling with a factional split and declining electoral fortunes.

The resignation highlights the deepening cracks in the party's leadership structure and raises questions about its ability to maintain unity in the face of mounting political pressures.
